How do you determine year by serial number?

To determine the year of manufacture by serial number, you generally need to refer to the manufacturer's specific serial number decoding guide, as different companies have different systems. Often, the serial number will include a code or digits that correspond to the year of production. For example, in some cases, the first few digits might represent the year, while in others, a specific letter may denote the year. Always check the manufacturer's documentation or website for accurate decoding methods.
